Climate mitigation in focus

Rising environmental and climate mitigation pressures mean that more and more companies are looking for flexible and cost-efficient solutions to improve their carbon footprint. CO2 emitters like power companies want to avoid CO2 emissions. Also in other industries relatively concentrated streams of CO2 occur inevitable. Re-utilisation of CO2 is improving the carbon footprint.

Separating and reusing CO₂

One solution is to extract CO2 from off-gas streams that would otherwise be vented to the atmosphere. This is referred to as carbon capture. Once captured, the CO2 can be purified and liquefied, and then supplied to a huge diversity of applications from horticulture and welding to cryogenic cleaning and carbonated drinks. Carbon recycling not only contributes to climate and environmental protection, it also has the added bonus of low supply costs and immediate availability of the gas. Alternatively, the CO2 can be sequestrated – in other words, stored underground – to mitigate the climate impact of industrial processes that rely on the combustion of fossil fuels.

Typical sources of CO₂-rich off-gas streams include

Chemical plants (for ammonia and ethanol)

Refineries

Hydrogen production

Fossil fuel power plants

Industries such as iron and steel, cement, pulp and paper, etc.

Here at Linde, we are firmly committed to reducing or managing harmful emissions from industries such as these. Our clean technology portfolio includes innovative ways to reduce CO2 emissions through processes aimed at capturing, purifying and liquefying CO2.

Covering the full carbon capture chain

Building on our long-standing expertise in combustion and carbon recovery technologies, we are actively advancing two strategies to reduce CO2 levels from flue gases:

Oxyfuel combustion, combusting the fuel with pure oxygen to create mainly steam and CO2, which can be easily separated from the flue gas

Partner of choice for CO₂ purification and liquefaction

World leader in cryogenic technology, we have designed and supplied the world’s largest CO2 purification and liquefaction plant, delivering the industry’s highest availability levels. Our plants are the solution of choice where performance, quality and reliability are a must. Depending on your needs, we cover the full solution lifecycle – extending from feasibility studies through engineering, supply and construction right up to all-inclusive turnkey solutions (engineering, procurement, construction) on a lump-sum basis.

Complementing our customised offering, we deliver a range of modular plants. These are designed to maximise cost efficiencies, reduce risks and accelerate time to solution through standardisation and pre-testing, while still giving you the flexibility you need to adapt to variations in feed gas sources. Design highlights include a compact footprint and ease of maintenance.

The capacity and purity you want

Our broad CO2 plant portfolio supports on-stream applications requiring gaseous or liquid CO2 with purity levels of up to food grade quality. Capacities start from 30 metric tonnes per day for modularised units with a single train. Customised solutions or several modular trains support capacities beyond 360 t/d.
